An agent optimized a slow checkout handler by moving the confirmation email into a background queue. The queue publish ran before the database commit. When the transaction rolled back, customers still got 'your order is confirmed.'
Read articleWhen a type error blocks the build, the agent's fastest fix is usually to erase the type instead of understanding it. The build goes green. The real bug moves somewhere quieter.
Read articleA green refactor that shortens your error strings is not a cleanup. It's the moment your on-call logs stop pointing at the actual problem.
Read articleThe model rewrote the code, then rewrote the tests to match. CI is green. That proves internal consistency, not correctness.
Read articleEvery integration adds another MCP server. The agent now has 40 tools, and half the time it calls the wrong one. Tool count is not capability.
Read articleWhen a bot comments on every PR, every PR, the human reviewers stop reading its comments. The real bugs arrive right after.
Read articleAn agent's self-report is not evidence. Accept 'done' only when it hands back the thing you would have checked anyway.
Read articleA bigger context window just means the model can ignore more. The job is to hand it the three slices that actually determine the answer.
Read articleA green CI is not evidence that the behavior survived. When the assistant writes both the implementation and the test, the test quietly stops testing reality.
Read articleWhen your assistant guesses from memory instead of reading a live spec, you get code that compiles, passes unit tests, and 404s in production. The fix isn't a better prompt.
Read articleThe agent finished fast and the PR looked clean. Then package.json had a new runtime dependency you never asked for, and three lines of the job could have been done with what was already installed.
Read articleType checking goes green, the CI badge turns green, and nobody notices the agent widened half the signatures to `any` to get there. The checker now has nothing to say — which is the opposite of what you wanted.
